Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a heat pump type window-mounted air conditioner, and is particularly designed to improve the cooling capacity in the summer and maintain the heating capacity in the winter when the outside temperature is low. It provides structure.

"Prior Art" As shown in Fig. 3, a conventional heat pump type window-mounted air conditioner introduces condensed water from an indoor heat exchanger onto the main body base 21, and also transfers this condensed water to an outdoor heat exchanger. By scattering the air during rotation of the propeller fan 23 with a slinger ring that faces the air conditioner 22, the cooling capacity during cooling operation is improved.
In addition, during heating operation, if condensed water remains on the main body base 21 for any length of time, it may freeze and destroy the propeller fan 23. To prevent this, when the fan 23 rotates, the wind pressure causes the water on the main body base 21 to freeze. By taking advantage of the fact that an anhydrous zone is created in which water does not accumulate, and by forming a water drain port 24 in this zone, condensed water introduced into the main body base 21 is discharged when the propeller fan 23 is rotated. When the fan 23 stops, this water drain port 2
It was designed to drain water quickly from 4 onwards.

"Problems to be Solved by the Invention" However, according to the conventional structure, the water drain port 24 is opened directly on a plane with respect to the main body base 21, so that the wind pressure of the propeller fan 23 is reduced. If there is not enough, the main body base 2
1 and the propeller fan 23, the formation of an anhydrous zone on the main body base 21 will be insufficient, and the condensed water on the base 21 will be scattered to the outdoor heat exchanger 22 when the propeller fan 23 rotates. This has the disadvantage that water is drained from the drain port 24 before the water is drained.

"Means for Solving the Problems" The present invention eliminates the above-mentioned conventional drawbacks, and includes a slinger ring for scattering condensed water introduced onto the main body base and spraying it onto the outdoor heat exchanger. In an air conditioner equipped with a propeller fan, a water drain port is formed in the anhydrous zone where water is no longer donated due to wind pressure in the tangential direction of the wing tip of the fan, and a drain port is formed in the fan at the peripheral edge surrounding the water drain port. A protruding edge of a required height is formed on the opposing sides.

``Embodiment'' The present invention will be explained with reference to an embodiment shown in the figure below. 1 is a main body base of a heat pump type window-mounted air conditioner, and on the main body base 1 is a partition plate 2 containing a heat insulating material. The indoor side divided by the partition plate 2 is provided with an indoor heat exchanger 3 and a Shirotsko fan 4 facing it, and the outdoor side is also provided with an outdoor heat exchanger 5 and an opposing side heat exchanger 3. Propeller fan 6 with slinger ring and the same fan 6
A baffle plate is disposed to surround the air guide plate, and a driving fan motor 7 is disposed between the Shirotsuko fan 4 and the propeller fan 6, and a compressor is disposed on the side thereof.

The main body base 1 of the air conditioner is configured to introduce condensed water received in a dew pan provided at the lower part of the indoor heat exchanger 3 to the outdoor side, and the propeller fan 6 with a slinger ring is installed. A water drain port 8 is formed in the anhydrous zone, which is located on the opposite half of the plane opposite to the rotation of the propeller fan 6 and receives wind pressure in the tangential direction of the blade tip of the propeller fan 6 and no longer receives water. As shown in FIG. 2, a projecting edge of a required height is formed by punching or the like, and an arcuate shape of a required height is formed on the side of the peripheral edge surrounding the water drain port 8 facing the propeller fan 6. A plurality of protruding edges 9 are formed.

"Function" With the above configuration, during cooling operation, condensed water from the indoor heat exchanger 3 is introduced to the outdoor side of the main body base 1 through the dew pan, and this condensed water is transferred to the outdoor side heat exchanger when the propeller fan 6 rotates. It is scattered and sprayed on the side of the vessel 5.

In this case, the wind from the propeller fan 6 hits the outdoor heat exchanger 5 side, increasing wind pressure and making it difficult for water to accumulate. On the other hand, an annular projecting edge is formed on the opening edge of the drain port 8 provided in this vicinity, and an arc-shaped edge of a required height is formed on the peripheral edge surrounding the drain port 8 on the side facing the fan 6. By forming the plurality of projecting edges 9, the flow of water is received by the projecting edges 9 during operation of the propeller fan 6, and drainage from the water drain port 8 can be prevented. Furthermore, by forming a plurality of protruding edges 9, the water level can be reliably lowered between them to prevent drainage. Furthermore, when the propeller fan 6 is stopped, the high wind pressure area is eliminated and water can be reliably drained from the water drain port 8 over the projecting edge 9.

``Effect of the invention'' As described above, in the present invention, an appropriate height is provided on the side facing the propeller fan of the periphery surrounding the water drain hole formed in the main body base of the heat pump type window air conditioner. By forming the protruding edge 9, even if the anhydrous zone on the main body base is insufficiently formed during the operation of the propeller fan in the cooling operation, the protruding edge can receive the flow of water. It is possible to reliably lower the water level and prevent drainage from the water drain port side, and when the propeller fan is stopped, water can be reliably drained from the water drain port beyond the projecting edge. This makes it possible to improve the ability of the cooling operation during the cooling operation in the summer. Furthermore, it is possible to maintain the heating operation when the temperature outside the room is low in winter, and to prevent the outside outside from freezing.
